Application led September 25, 1918. Serial No. 255,677.

To all whom t may concern Be it known that I, ROBERT PERLICK, a citizenof the United States, and resident of Milwaukee, in the county ofMilwaukee and State of lVisconsin, have invented certain new and usefulImprovements in Oil-Burners; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention is directed to new and useful improvements in oil burnersof that type wherein oil is supplied to a burner member including a fueltrough having disposed therein a relatively stationary incombustiblewick body of asbestos or the like, and having a depending tube slidablein a supply pipe, the regulation of the flame being procured by raisingand lowering the burner bodily to thus vary its relation to the fuelsupply level, and my invention relates more particularly to means forprocuring movement of the burner member.

It is in general my object to simplifyand otherwise improve thestructure and to increase the efficiency of devices of this character.

It is more particularly my object to provide a burner operatingmechanism which may be constructed mainly of stamped sheet metal andretained in place by its interlocking engagement with the main supplypipe and burner branch of a stove.

A further object resides in the provision of means for adjusting the'capof a packing gland for the burner tube and supply pipe, whereby the capis normally held against threading movement, and may be readilytightened.

With the above and other objects and advantages in View, which will beapparent as the description proceeds, my invention resides in the novelfeatures of construct-ion, combination and arrangement of parts ashereinafter more particularly described and defined by the appendedclaims.

In the accompanying drawings:

Fig. 2 is a front elevational view of the stove.

Fig. 3 is a rear view of one of my improved burner operating-mechanisms, the burner operated thereby being shown insection.

Fig. 4 is a side View of the mechanism, with portions thereof insection.

rReferrin now more particularly to the accompanying drawings, there isshown an oil burning stove including a main burner chamber A'having agrid a and having disposed under the grid a series of burners Cprojecting into hoods D of conventional nature interposed between theburners and grid. A main supply pipe E extends from the fluid levelchamber f of a reservoir F disposed at one end of the stove. Theconstant level chamber is provided in the usual manner with a valvedneck portion conventionally designated at g in Fig. 3, Wherebya constantlevel line L may be maintained in such relation to the burners C thatthe bottom portion of the burners may be moved to lie either above orbelow thislevel line, the main supply pipe E being extendedlongitudinally in the main burner chamber A below the level line andbeing provided with upstanding supply pipe branches e located in avertical plane at the forward sides of the burners C, said burners beingin the form of annular narrow troughs having their side walls slightlydivergent upward for wedging insertion therebetween of an annular wickband 0 formed of asbestos or similar non-combustible porous material.Each of the burners is supplied with oi-l' and is supported solely by adepending stem, c which is telescopically slidable in a correspondingsupply pipe branch e, the degree -of sliding movement of the stempermitting the lower portion of the burner to move pastl the fluid levelline L. A `packing gland for the stem is provided including a cap c2'threaded on the upper end portion of the supply pipe branch andconfining packing material between the top of the cap and the end of thepipe branch', said cap being provided with Wrench faces, whereby thegland may be tightened as desired incidental to yielding of the packingmaterial in continued operation of the burner.

My improvedmechanism for raising and lowering each burner to controlvthe feed of oil through the wick includes a bracket formed of a sintgleplate of metal intermediately bent to orm a horizontally extending arm10 and a vertically extending arm l1, the inner end portion of the arm10 belng apertured to snugly receive the supply pipe branch e. Thevertical arm 11 has its lower portion bent laterally forward and thendownwardly to provide a shoulder 12 resting on the main supply pipe E,and a substantially vertical portion 13 disposed forwardly of andprojecting below the pipe. Struck outwardly from the intermediateportion of the bracket arm 11 and bent vdownwardly below the shoulder isa tongue 14, the main supply pipe E being confined between the tongue 14and arm end portion 13. Upward displacement of the bracket is preventedby a cotter pin 15 passed through the arm portion 13 and the tongue 14below the pipe, and thus the bracket is firmly secured to the supplypipe structure in a 'manner permitting a maximum economy in forming thebracket, and a minimum expenditure of labor in assembling the bracket onthe supply pipe and branch, the major securement of the bracket beingprocured simply by the interlocking relations assumed in inserting thesupply pipe branch in the apertures of the arms 10 and 11 of thebracket. The forward end of the horizontal bracket arm is downwardlydirected at 16 to form an attaching flange to which is secured the lowerportion of a vertical dial plate 17.

This downwardly turned bracket arm portion, in conjunction with thelower portion of the dial plate is also utilized to form the journal forthe forward end of an operating shaft 18 which extends under the bracketarm at one side of the supply pipe branch e and has a second journal inthe upper portion of the vertical arm 11 of the bracket. Immediatelyrearwardly of the arm 11 this shaft is squared for the recept-ion of theheaded end of a crank arm 19, the extremity of the shaft being swaged at20 in Fig. 3 to secure the crank arm on the shaft. Pivoted to theextremity of the crank arm is a link 21 which is also pivoted to theup-turned free end of a lug A22 projecting inwardly from the lowerportion of the burner at its juncture with the supporting and supplytube c. Thus, upon rotating the shaft18, the burner C may be raised orlowered so that its bottom portion is disposed either above or below theHuid line L. To procure this rotation of the shaft, and at the same timeprocure indication of the position of the burner relative to the fluidlevel line, the end portion of the shaft outwardly of the dialplate 17is directed obliquely, and a bar 23 is riveted at an intermediateportion to this oblique end of the shaft, the major portion of the barextending downwardly to form a handle. The remaining portion of the barbeing inclined toward the dial by reason of the attaching portion of theshaft, forms an indicator cooperating with certain symbols on the dial,the handle being spaced forwardly by reason of this oblique inclinationto permit a most ready and convenient manipulation thereof.

To hold the shaft 18 against longitudinal movement, and also to providea support for a leaf spring 24 engageable with the head of the link 19,la vertical plate 25 is secured to the sideof the bracket adjacent theshaft by `the attachment of its laterally turned upper end 26 to thehorizontal arm of the bracket, said plate extending rearwardly of 'thebracket and being provided in its rearward portion with a verticallyelongated slot receiving the head of the link 19, the engagement of saidhead in. the' slot obviously preventing longitudinal movement of theshaft 18 to which it is attached. The leaf spring 24 is secured at itslower end to the lower rear portion of the plate and bears against thatportion of the head which projects through the slot, the head having itsperiphery rounded concentric with the shaft, whereby a frictional detentis afforded by the spring in the various rotative positions of theshaft, and to hold the burner more positively in normal burningposition, and at the same time aid the operator. in attaining thisnormal burning position, the head of the link is provided with a notch27 in which the transversely bowed free extremity .'-of the springengages when the link 19 is disposed in a substantially horizontalposition, procuring a position of the burner intermediate of its limitsof vertical movements, the lower edge of the wick being disposedslightly below the' fluid level line. L in. this position.

It is noted that the link may swing through an are of substantially1800,' engaging in either limit of movement against the rearward portionof the wall plate 25, and in its upward limit of movement, it is notedthat the upper end of the lin-k swings for abutment with the plate,slightly past a dead center line connecting the axis of the shaft 18with the pivotal axis of the burner lug 22, whereby the burner is thuslocked in raised position.

The indicator dial 17 is provided with symbols 28 and 29 at oppositesides of the shaft 18 indicating respectively the upper and lower limitsof movement imparted to the burner by the handle and indicator bar 23,the burner being raised to its limit of upward movement, consequentlycutting otl' supply of oil thereto when the indicator points to-thesymbol 29, and being depressed to its lower limit of movement when theiudicator points to the symbol 28 to supply an excess of oil to theburner to facilitate lighting the burner. Intermediate of the symbols 28and 29 there are provided a series of renacer Continued raislng andlowering move.

ments of the burners loosens the packing glands of the supporting tubec, and it is necessary from time to time to tighten the gland caps o2,to take up thislooseness. l provide a tightening means for the cap in amost compact and readily operated mannen which means is associatedpermanently with the burner structure as is necessary in acommerciallyattractive article. Thus, a wrench is provided including anannular closed head 3l apertured to receive the cap, this wrench headbeing provided with upwardly and inwardly extending lingers 32 adaptedto seat l on the cap. A downwardly olset handle 32 extends from thewrench head and is provided with a slot 33 which normally receives afinger 34 struck upwardly from the horizontal arm 10 of the bracket,whereby a lock for the cap is normally afforded preventing any tendencyto unscrewing movement which would be set up in operation ofthe burner.To tighten the cap c2, itis merely necessary to lift the wrench handle32 from engagement of the finger 3l in its slot 33, and then to rotatethe' wrench and cap, the wrench being subsequently engaged with otherwrench faces of the cap and restored to its locking co-action with thefinger 84.

An. exceedingly simple device has thus been provided for tightening thecap which Vmay be readily manipulated by persons not necessarilyfamiliar with mechanical operations, it being noted that a maximumcoinpactness of structure is permitted incontradistinction to heretoforecontemplated arrangements. Attention is further directed to the factthat loss of the wrench is positively prevented by reason of the closedshape of its head, so that the head is interlocked at all times eitheron the cap 0r with respect to the tube ,0.

1t w1ll be particularly noted that by the disposition ofthe suppl tube cand the connecting link 21 at the orward side portion of the burner C,the c'enter of gravity of the burner isdisposed a considerable distancelaterally thereof, and thus a frictional binding action is set up whichnormally holds the burner against downward movement under influence ofgravity, this holding being relied upon to maint'ain the burner in itsvarious burning ositions other than the intermediate norma burningposition in which the spring 24 engages in the notch 27 of the head lofthe crank arm i9, said spring also, of course exerting some frictionalactionagainst the periphery of the head when disengaged from the notch.
